Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetism, insulation, self-lubrication, high speed, etc. In high speed, high temperature, low temperature, big temperature change, vacuum, insulation requirements, non-conductive magnetic and other harsh working environment, high-performance ceramic bearings are the ideal bearing to replace the current use of steel bearings. The service life of ceramic bearings is more than 3 times higher than that of steel bearings, which can significantly reduce downtime and improve the operating efficiency of machinery.
Mascera has developed ceramic bearings in silicon nitride ceramic and zirconia ceramic for a number of standard sizes, they are regularly in stock for fast delivery.
Main Properties
| ✓ high temperature resistance | ✓ cold resistance |
| ✓ wear resistance | ✓ orrosion resistance |
| ✓ anti-magnetism | ✓ insulation |
| ✓ self-lubrication | ✓ high speed |
Main Type
1. ZZ type:Bearing is sealed by PTFE or PEEK retainer
2. Bearing comes without seal on any side
3. Bearings are made of Si3N4 or ZrO2 ceramic
4. Material of Balls Type：Si3N4 or ZrO2 Ceramic Balls
5. Bearing Cage：Si3N4 / ZrO2 / PTFE / Nylon
6. Bearing Model：6000/6300/1600/R series
Advantages
1. It exhibits exceptional resistance to corrosion and can be effectively used in environments with strong acid, strong alkali, and seawater.
2. The Zirconia ceramic maintains its strength and hardness even at high temperatures of up to 850°C.
3. It is non-magnetic, insulating, and can be safely employed in magnetic fields without conducting electricity.
4. It possesses high rigidity and strength, with a hardness twice that of bearing steel and an elastic modulus approximately 1/3 higher.
5. The Zirconia ceramic allows for high-speed rotation due to its lightweight nature, minimizing centrifugal forces during rotation.
6. Its linear expansion coefficient is 3.2×10-6/K, roughly 1/4 that of bearing steel.
7. It demonstrates excellent chemical resistance, mechanical strength, impressive toughness, and low thermal conductivity.
